The answer is b because when you add in the scale factor of 3 it makes all of the coordinates 3 times larger (for example -4 * 3 = -12 and 3 * 3 = 9 so P" = (-12, 9))
The change in temperature has dipped from -2 degrees Celsius to -10 degrees Celsius, meaning there is a negative diversification.
-10 degrees Celsius is equal to 14 degrees Fahrenheit.
-2 degrees Celsius is equal to 28.40 degrees Fahrenheit.
Thus, the temperature gap is 14.40 degrees Fahrenheit.

48 would be 75% or 3/4 of the full price, so dividing it by 3 gives us 16, or 1/4. multiply by 4 to get 4/4, the whole price
We know that:
1 mile = 5280 ft
1 minute = 60 sec
Therefore to convert this we simply use the conversion
factors:
(30 ft / s) * (60 s / 1 min) * (1 mi / 5280 ft) = 0.34 mi
/ min
So we got 0.34 miles per minute.
